My interpretation: Abstraction can be interpreted as a result of data hiding. The user of the class has only access to what he needs (setter, getter) while the complications are hidden away, so he/she only sees a 'summary' of what's going on, the abstraction.

Data hiding (i interpret this as encapsulation) is where the Class make its data only accessible by itself. Meanwhile Abstraction as HonFu said, is an interface for outside element to interact with its data without changing them directly
